Abstract
In detecting a fuel injection timing in a diesel engine, a crank angle reference position is detected from rotation of a member rotatable in association with rotation of the engine, said member being disposed outside a fuel injection pump. While, in the fuel injection pump, a predetermined pump angle is detected from rotation of a member for converting rotary motion of a pump driving shaft into reciprocatory motion of a fuel pressure-feed plunger relative to the pump driving shaft, whereby the fuel injection timing is determined from a phase difference between the crank angle reference position and the predetermined pump angle. With this arrangement, the fuel injection pump can be assembled onto the engine without accurate measuring and an accuracy in detecting the fuel injection timing equal to or exceeding that in the conventional case can be obtained by more simplified adjustment than in the conventional case or with no adjustment.
